How this pay compares

At $90/hr (the midpoint of $60 to $120), this role pays more than 74% of the 51 open chemistry roles with a listed pay range, above the median of $83.

Open chemistry roles that ask for a PhD have a median of $79/hr (32 roles).

Among platforms with 10 or more priced chemistry roles, Mercor has the highest median ($85/hr across 11 roles) and OpenTrain AI the lowest ($75/hr across 25).

OpenTrain AI roles that closed since late October stayed listed a median of 31 days (122 roles). OpenTrain AI posted this one 6 days ago.

Computed from 2,746 open roles we track across Mercor, micro1, Handshake AI, Alignerr, Appen and OpenTrain AI, refreshed daily. Midpoints of listed ranges; “up to” ceilings are left out of medians.

Tax
Contract pay arrives with no tax withheld. A US contractor at this rate and these hours would set aside about $1,972 a month for self-employment tax plus federal income tax at the 12% bracket (25%, before state tax). Outside the US, your own country's rules apply.

The work

You will create written scenarios that test whether AI models can reason accurately about biochemistry and molecular biology. Your work will cover assay design, molecular mechanisms, experimental logic, pathway accuracy, data interpretation, and appropriate uncertainty.

You will also write reference answers and review model-generated responses. The role requires identifying fluent answers that contain biochemical errors and explaining the correct reasoning in clear, teachable language.

  • Write realistic molecular biology scenarios, from assay design through experimental data interpretation.
  • Create reference answers that explain the mechanisms behind each conclusion.
  • Weigh relevant pathways, experimental evidence, and uncertainty.
  • Grade AI-generated answers for scientific accuracy and experimental reasoning.
  • Identify biochemical errors that require trained scientific judgment to detect.
  • Explain conclusions using mechanisms and data rather than general textbook summaries.

What it pays and takes

This is fully remote, asynchronous independent contractor work. You can set your hours and adjust your weekly workload while contributing to ongoing project work.

  • Pay: $60 to $120 per hour, paid weekly via Stripe.
  • Schedule: Part-time, with a commitment of 20 or more hours per week.
  • Location: Open to candidates in the eligible countries listed for this role.
  • Language: Fluent written English for documenting complex scientific reasoning.
  • Education: An advanced degree in biochemistry, molecular biology, or a closely related field, or equivalent research experience.
  • Experience: At least two years of research or industry experience in molecular life science.
  • Technical background: Hands-on experience with cloning, protein work, sequencing, assay development, or similar techniques.
  • Helpful background: PhD-level training, peer-reviewed publications, biotechnology or pharmaceutical research, bioinformatics, or structural biology.
